The 1989–90 Los Angeles Kings season, was the Kings' 23rd season in the National Hockey League. It saw the Kings compile a record of 34-39-7 for 75 points, good enough for fourth place in the Smythe Division. They defeated the defending Stanley Cup champion Calgary Flames in the first round of the playoffs before falling to the eventual Stanley Cup champion Edmonton Oilers in the second round. For the Kings, this was the second consecutive year that they eliminated the defending Stanley Cup champions in the first round of the playoffs, only to be swept in the following round by the eventual Cup champions. In both years, they involved both teams from the province of Alberta.
